[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: For a hot rolling mill that facilitates the biting of billets and prevents slipping, through the setting of a fixing mechanism, when it is necessary to fix a billet, first adjust the telescopic column to an appropriate height, and then start the electric push rods respectively. The electric push rods push the fixing slots through spherical joints. Due to the existence of the spherical joints, the angle of the fixing slots can be appropriately deflected when using the electric push rods. When adjusted to an appropriate angle, the billet can pass through the storage rack. The billet is transmitted from the storage rack to the load-bearing platform. Since a guiding groove is provided on the load-bearing platform, the billet will enter the fixing mechanism through the guiding groove. The guiding groove plays a role in roughly positioning the billet. At this time, turn on the motor, and the motor drives the active limit turntable to rotate.

Therefore, the motor drives the rotation of all the rollers. The rollers clamp the billet to a certain extent and apply a frictional force for forward movement, limiting the billet in the left and right directions to a certain extent. After passing through the rollers, the billet enters below the drum. Since the drum rotates around the rotating shaft, when the billet passes through the drum, its up and down directions are limited to a certain extent. Finally, the billet enters the hot rolling body and undergoes hot rolling by the rolling rolls. Through this mechanism, the problems existing in the prior hot rolling mill during the billet biting process are effectively solved, the production efficiency and product quality are improved, and at the same time, the energy consumption and maintenance cost are reduced.

[0020] Please refer to Figures 1-4 , the present invention provides a technical solution: a hot rolling mill that is convenient for the billet to bite and prevent slipping, including a storage rack 1, a foot 2 is fixedly connected to the lower surface of the storage rack 1, a load-bearing platform 3 is fixedly connected to one side surface of the storage rack 1, a foot 4 is fixedly connected to the lower surface of the load-bearing platform 3, a guide groove 5 is fixedly connected to the upper surface of the load-bearing platform 3, a fixed tabletop 6 is fixedly connected to one side surface of the load-bearing platform 3, a table foot 7 is fixedly connected to the lower surface of the fixed tabletop 6, a fixing mechanism 8 is arranged on the upper surface of the fixed tabletop 6, a hot rolling body 9 is fixedly connected to one side of the fixed tabletop 6, and a rolling roll 10 is fixedly connected to the inner surface of the hot rolling body 9;
[0021] The fixing mechanism 8 includes a base 801, frame columns 802, frame beams 803, electric push rods 804, spherical joints 805, fixing grooves 806, rollers 807, rollers 808, a driving limit turntable 809, a driven limit turntable 811, a belt 810, a motor 812, fixing blocks 813, telescopic columns 814, rotating shafts 815 and rotating cylinders 816. One side surface of the fixed tabletop 6 is fixedly connected with the base 801. The upper surface of the base 801 is fixedly connected with the frame columns 802. The upper surface of the frame columns 802 is fixedly connected with the frame beams 803. The inner surface of the frame columns 802 is fixedly connected with the electric push rods 804. One side surface of the electric push rods 804 is fixedly connected with the spherical joints 805. One side surface of the spherical joints 805 is rotatably connected with the fixing grooves 806. One side surface of the fixing grooves 806 is rotatably connected with the rollers 807. One side surface of the rollers 807 is fixedly connected with the rollers 808. The upper surface of the rollers 807 is fixedly connected with the driving limit turntable 809. One side surface of the driving limit turntable 809 is in contact with the belt 810. One side surface of the belt 810 is in contact with the driven limit turntable 811. The upper surface of the driving limit turntable 809 is fixedly connected with the motor 812. One side surface of the fixed tabletop 6 is fixed with the fixing blocks 813. The upper side surface of the fixing blocks 813 is fixedly connected with the telescopic columns 814. One side surface of the telescopic columns 814 is fixedly connected with the rotating shafts 815. One side surface of the rotating shafts 815 is fixedly connected with the rotating cylinders 816. Through the settings of the base 801, frame columns 802, frame beams 803, electric push rods 804, spherical joints 805, fixing grooves 806, rollers 807, rollers 808, driving limit turntable 809, belt 810, driven limit turntable 811, motor 812, fixing blocks 813, telescopic columns 814, rotating shafts 815 and rotating cylinders 816, when in use, the telescopic columns 814 are adjusted to a suitable height, and then the electric push rods 804 are started respectively. The electric push rods 804 push the fixing grooves 806 through the spherical joints 805. Due to the existence of the spherical joints 805, the angle of the fixing grooves 806 can be appropriately deflected when using the electric push rods 804. When adjusted to a suitable angle, the billet can pass through the storage rack 1. The billet is transmitted from the storage rack 1 to the load-bearing platform 3. Since the guiding grooves 5 are arranged on the load-bearing platform, the billet will enter the fixing mechanism 8 through the guiding grooves 5. The guiding grooves 5 play a role in roughly positioning the billet. At this time, the motor 812 is turned on, and the motor drives the driving limit turntable 809 to rotate. Also, because the belt 810 is in contact with the driving limit turntable 809 and the driven limit turntable 811, that is, the driving limit turntable 809 drives the driven limit turntable 811 to rotate together, and the driving limit turntable 809 and the driven limit turntable 811 are fixedly connected with the rollers 807, and the rollers 807 are fixedly connected with the rollers 808, so the motor 812 will drive all the rollers 808 to rotate. The rollers 808 clamp the billet to a certain extent and apply a frictional force for forward movement, and limit the billet in the left and right directions.The billet enters below the roller after passing through the roller 808. Since the roller rotates around the rotating shaft 815, when the billet passes through the roller, certain limits are imposed on its up-and-down direction. Finally, the billet enters the hot rolling machine body 9 for hot rolling of the rolling rolls 10. Through this mechanism, the problems existing in the billet biting process of the existing hot rolling mill are effectively solved, the production efficiency and product quality are improved, and at the same time, the energy consumption and maintenance cost are reduced.,
[0022] Furthermore, the guide groove 5 is fixedly connected to the table leg 7 through the fixed tabletop 6. Multiple groups of rollers 808 are symmetrically arranged with respect to the central axis of the fixed groove 806. Through the settings of the fixed groove 806 and the rollers 808, during use, the symmetrical layout of the rollers 808 helps to balance the force on the billet during the biting process, reduce the risk of skew or distortion, and thus improve the stability and accuracy of the billet biting.
[0023] Furthermore, the electric push rod 804 is fixedly connected to the base 801 through the frame beam 803. The size of the active limit turntable 809 matches the size of the driven limit turntable 811. Through the settings of the base 801, the frame beam 803, the electric push rod 804, the active limit turntable 809 and the driven limit turntable 811, during use, since the size of the active limit turntable 809 matches the size of the driven limit turntable 811, this design can ensure the synchronous rotation and smooth power transmission between the two turntables. Through the connection of the frame beam 803 and the base 801, the electric push rod 804 can achieve precise position adjustment to ensure that the position of the billet during the biting process is accurate. This connection method also helps to maintain the stability of the electric push rod 804 in different working states and improve its adjustment accuracy.
[0024] Furthermore, the fixed groove 806 is symmetrically arranged with respect to the central axis of the fixed tabletop 6. Multiple groups of electric push rods 804 are symmetrically arranged with respect to the central axis of the frame beam 803. Through the settings of the fixed tabletop 6, the frame beam 803, the electric push rod 804 and the fixed groove 806, during use, since the fixed groove 806 is symmetrically arranged with respect to the central axis of the fixed tabletop 6, it can ensure that the billet is evenly supported when entering the fixing mechanism 8, which helps to improve the stability of the billet biting. The electric push rods 804 are symmetrically arranged with respect to the central axis of the frame beam 803. This layout can ensure uniform distribution of the thrust, reduce the skew of the billet when entering the fixing mechanism 8, and improve the stability of the overall structure.
[0025] Further, multiple sets of driven limiting turntables 811 are symmetrically arranged with respect to the central axis of the fixed slot 806, and multiple sets of motors 812 are symmetrically arranged with respect to the central axis of the fixed table 6. With the arrangement of the driven limiting turntables 811, during use, the symmetrical arrangement of the driven limiting turntables 811 helps to ensure that the billet accurately enters the fixing mechanism, reduces the resistance during the biting process, and improves the conveying efficiency of the billet. This design can also increase the contact area between the billet and the fixing mechanism, thereby increasing the friction force and helping to prevent the billet from slipping during the biting process.
[0026] Further, the rotating shaft 815 is fixedly connected to the fixed block 813 through the telescopic column 814, and multiple sets of frame columns 802 are symmetrically arranged with respect to the central axis of the fixed table 6. With the arrangement of the fixed block 813, the telescopic column 814, and the rotating shaft 815, during use, the design of the telescopic column 814 can be adjusted in height as needed to adapt to billets of different sizes, improving the adaptability and flexibility of the equipment.
[0027] Further, the fixed block 813 is fixedly connected to the table foot 7 through the fixed table 6, and the frame beam 803 is fixedly connected to the foundation 801 through the frame column 802. With the arrangement of the fixed table 6, the table foot 7, the foundation 801, the frame column 802, the frame beam 803, and the fixed block 813, during use, the design that the fixed block 813 is fixedly connected to the table foot 7 through the fixed table 6 and the frame beam 803 is fixedly connected to the foundation 801 through the frame column 802 helps to improve the stability, biting efficiency, and product quality of the billet biting, while also reducing the wear and maintenance costs and improving the operation safety.
[0028] Working principle: Adjust the telescopic column 814 to an appropriate height, and then start the electric push rods 804 respectively. The electric push rods 804 push the fixed slots 806 through the spherical joints 805. Due to the existence of the spherical joints 805, the angle of the fixed slots 806 can be appropriately deflected when using the electric push rods 804. When adjusted to an appropriate angle, the billet can pass through the storage rack 1. The billet is transmitted by the storage rack 1 to the load-bearing platform 3. Since the guide slots 5 are provided on the load-bearing platform, the billet will enter the fixing mechanism 8 through the guide slots 5. The guide slots 5 play a role in rough positioning the billet. At this time, turn on the motor 812, and the motor drives the active limit turntable 809 to rotate. Also, because the belt 810 is in contact with the active limit turntable 809 and the driven limit turntable 811, that is, the active limit turntable 809 drives the driven limit turntable 811 to rotate together, and the active limit turntable 809 and the driven limit turntable 811 are fixedly connected to the roller shafts 807, and the roller shafts 807 are fixedly connected to the rollers 808, so the motor 812 will drive the rotation of all the rollers 808. The rollers 808 clamp the billet to a certain extent and apply a frictional force for forward movement, which limits the billet in the left and right directions. After passing through the rollers 808, the billet enters below the rollers. Since the rollers rotate around the rotating shaft 815, when the billet passes through the rollers, its up and down directions are limited to a certain extent. Finally, the billet enters the hot rolling machine body 9 for hot rolling by the rolling rolls 10. Through this mechanism, the problems existing in the billet biting process of the existing hot rolling mill are effectively solved, the production efficiency and product quality are improved, and at the same time, the energy consumption and maintenance cost are reduced. Among them, the model of the electric push rod 804 is YS-NZ100-12A, and the model of the motor 812 is YE2-132S-4.
